The new design for the $100 note made its debut on April 21 during a ceremony at the Department of the Treasury's Cash Room. The U.S. government redesigns currency in order to stay ahead of counterfeiters and protect the public. The unveiling of the $100 note is the first step in a global multi-government agency public education program implemented by the Department of the Treasury, the Federal Reserve Board and the U.S. Secret Service, to educate those who use the $100 note about its changes before it begins circulating on February 10, 2011.
